So, with it showing Renslayer's arrival to 1868 being a part of the "Sacred Timeline" and Loki and Mobius arriving in 1893 as a "Branched Timeline" it seems like Victor Timely was born around the late 1850s/early 1860s in the Sacred Timeline and it branched off the moment he got the book. Maybe someone who has more comic Kang knowledge can enlighten me, but I thought all the Kangs were born in the future and their appearances in the past were due to time travel. For example, Rama Tut and Iron Lad. Are there Kangs that were born at different points in time rather than traveled through it, as the episode seemed to imply?
EDIT: So, my take is He Who Remains placed the Victor variant in the Sacred Timeline as a contingency plan. If HWR hadn't died, Victor would have lived a normal life on the Sacred Timeline with no knowledge he was a variant. However, knowing Sylvie was going to kill him, HWR gave Miss Minutes the mission to give Victor the book, creating the branched timeline in the hopes he would take over. How does that sound?
